episode 0 is a preparation for season 2, its normal episode contain the required information to understand how it starts as it is in season 2 , not that it is a must but helps in following up on what happened , its a normal episode with normal length , I recommend watching it before starting season 2.
some might find it useless to do episode like this and I understand , like why don't they just start the season with this episode then continue , first episode still not out but I guess its a follow up to this so I could relate.
for the episode itself it was good , didn't notice a difference in animation or sounds compared to season one, sound track in season 1 was very beautiful and so in this episode .
